To (LZZ whom it may concern:

Be it known that I, EARNEST FINCH, a citizen of the United States, residing at Akron, in the count-y of Sunnnit and State of Ohio, have invented a new and useful Chimney Cap, of which the following is a specifi ation.

One object of this invention is to' provide a chimney cap which-is so constructed that a down draft through the chimney, due to a gust of wind, will be prevented. Another object of the invention is to provide a chimney cap which will prevent rain and snow from finding its way into the chimney.

Another object of the invention is to provide a chimney cap which will retain heat for a long time, thereby promoting the draft through the chimney.

It is within the province of the disclosure 39 to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in View, which will appear as the description pro-- ceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, with in the scope of what is claimed, changes in W the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the drawings Figure 1 shows in elevation, a device con structed in accordance with the invention; Figure is a vertical section; Figure 3 is a cross section on the line 33 of Figure 2, the line 22 in Figure 3 indicating the cutting plan on which Figure 2 is taken; Figure 1 is a bottom plan of the top of the chimney cap.

The device forming the subject matter of this application comprises a tapered hollow body 1 having downwardly and outwardly slanting external surfaces 2 and provided with an opening 0 in its upper end, the body 1 carrying standards :1, between which are located openings 5, the standards supporting a table 6. A pyramidal top 7 is supplied and has an internal chamber 8. In the lower end of the top 7 a recess 9 is formed, the same defining a horizontal shoulder 10 and a depending flange 11, the flange 11 being supplied with a continuous, downwardly opening groove 12, The table 6 is received in the recess 9 and cooperates with the'shoulder 10, the top thus being supported from the body 1. The body 1 has inwardly projecting battles 14, provided with converging surfaces defining edges 15.

The numeral 16 marks a chimney which may be provided with a fine lining 17, a

portion of the lining upstanding as at 18,

to'form a sleeve. The lower ends of the baffles 1 1- rest on the upper end of the chimney 16, and the inner edges of the battles cooperate-with the sleeve portion 18 of the fine 17. Thus, the device is held on the top of the chimney against downward movementand against horizontal movement.

The bafl'les li set up in the body '1 high enough so that the lower edge of the body forms flange 19 extended downwardly below the upper surface of the chimney 16.

The air in the chamber 8 of the top 7 becomes heated and remains heated for a long time, even though the fire should be permitted to die down. The table 6, consequently, remains heated for a long period of time and the up-draft throughthe chimney is facilitated, it being well known that when the upward draft through a chimney strikes a cold object, the draft is checked. 1 Any water which runs downwardly on the top 7 will be received in the circumferential groove 12 and will be prevented from ent'ering the body 1 and finding its way into the chimney,the water falling on the surfaces 2 of the body, and being conducted away laterally.

lVhat is claimed is A device of the class described, adapted to be used in connection with a chimney having an upstanding sleeve,the device comprising a hollow body having internal transverse battles, the lower edges of which are adapted to rest on the chimney to support the device, the lower edges of the battles being spaced above the lower edge of the body, so that the lower edge of the body will form a depending flange adapted to extend about the chimney, the inner edges of the battles being adapted to engage the sleeve to space the flange from the periphcry of the chimney, a table disposed above the body, standards supporting the table upon the body, and a hollow top having a recess receiving the table, the top being sup ported on the table and being closed by the table to. form an air chamber located in the a path of the products proceeding from the as my own, I have hereto ahixed my signabody, the chamber serving to heat the table ture in the presence of two Witnesses.

for a time after the products have ceased to flow through the body, the table and the top being thick enough to prevent rapid conduction. y

In testimony that I claim the foregoing EARNEST FlNGI-l.
